High quality product for liquidation with minor scratches, not balanced and overstocked.
THis list includes a set of 3 pieces of 5kW wind generator blades which are made of reinforced fiberglass. These blades have been expertly designed and made to harness the wind power as much as possible. Its efficiency is graded at 0.49 in converting wind power to mechanical power, which is at the very top end ( the highest is 0.5). The exact same blades are used in commercial wind generators which perform much better than home-brewed ones. The shipping cost is for USA lower 48 states only. International and USA customers from other states need to get a shipping quote before placing the order.
Note: Please be careful comparing our blades to our competitor's blades. Their blades are poorly made with thick seam lines that severely change the aerodynamic characteristics and cause a lot of noise. Also, our blades are shipped to us pre-balanced and in matched sets in their own boxes. Our competition receives their blades in a large crate with all the blades thrown in, causing scratches and cracks - making them appear to be used. You will be very happy with the blades we send you.
